In cryptography, the Tiny Encryption Algorithm (TEA) is a block cipher notable for its simplicity of description and implementation, typically a few lines of code.It was designed by David Wheeler and Roger Needham of the Cambridge Computer Laboratory; it was first presented at the Fast Software Encryption workshop in Leuven in 1994, and first published in the proceedings of that workshop.
AES key schedule for a 128-bit key. Define: N as the length of the key in 32-bit words: 4 words for AES-128, 6 words for AES-192, and 8 words for AES-256; K 0, K 1, ... K N-1 as the 32-bit words of the original key; R as the number of round keys needed: 11 round keys for AES-128, 13 keys for AES-192, and 15 keys for AES-256 [note 4] W 0, W 1, ...

They differ in the word size; SHA-256 uses 32-bit words where SHA-512 uses 64-bit words. There are also truncated versions of each standard, known as SHA-224, SHA-384, SHA-512/224 and SHA-512/256. These were also designed by the NSA. SHA-3: A hash function formerly called Keccak, chosen in 2012 after a public competition among non-NSA designers ...
Basic Window commands These basic PC keyboard shortcuts will work on all applications, browsers, and programs, as well as Windows 10 and earlier versions including Windows 8.
M i denotes a 32-bit block of the message input, and K i denotes a 32-bit constant, different for each round. The security of MD4 has been severely compromised. The first full collision attack against MD4 was published in 1995, and several newer attacks have been published since then.
